Polygon (as opposed to Poygon). I couldn't edit the Subject line. (enhancement request - edit subject line, when editing post.)

Hi, Dan Hamilton recently produced a video with colouring  of surfaces in TBC (via material takeoff). That provided the added benefit of colouring surfaces in Earthworks (for the machines).

For applications (where we don't need material management / delineation) , it would be great to have an option to "colour by Polygons" for surfaces.

When we deliver earthworks projects, we're specifically dealing with soil (dirt). We would however like the quick option of colouring by polygons. This would quickly add to the featured/selected /referenced linework by enabling:

coloured delineation of: (for example)

• Building platforms 
• Road Corridors, 
• Suds / Drainage Basins,
• Transportation (Haul) routes, etc, etc
• overdig zones
• soil modification areas
• piled platforms,
• vibro piling platforms, etc
• stone placement areas, etc
• (If we could colour code our site (quickly), it could help operators and managers quickly ascertain workflows, while standardising a method / approach to delivery.

This is helpful for both internally produced TTMs and externally provided TTMs

Regards,

Julius

Funny you mention that. Its something I've always wanted in civil3d, as it would be useful for so many things.

I have my own surface program I will be adding that to, and its not just selecting by polygon, you would want a flood fill function that stops at tris whose angle is over some tolerance.

So you could flood fill pavement, and have it stop at the curb or gutter, as those tris would angle away sharper than pavement tris.

Thanks James, 

We often use colouring of surfaces in 12d, especially for showing data / surfaces / designs for screen presentation purposes.

The flood fill function you describe, is (I assume) similar to enabling colour by slope. 

We often use that also, as it helps define different grades for different purposes. i.e.  Steep batters that can't be worked by a dozer, or flat surfaces that may need a temporary surface water management  strategy to enable water dispersal to occur. Similarly as you've mentioned, for delineating features.

Have a look if this gets you close

the macro only works until V5.81, haven't tested the upgraded version yet.

It's been awhile since I've used the "Validate Area" command.  It's a bit in-depth for takeoff.  It will generate closed filled polygons from take off areas.  This should give you what you're after plus some more data.  At least I think it's what you're after.
